This disclosure relates generally to networked devices, pest controlsystems, specifically, insect control systems, and applications thereof.

2. Description of the Related Art

Insects, especially mosquitos, can present a major nuisance to enjoyingoutdoor activities. Also, such insects can present significant healthconcerns by spreading diseases. There are a variety of insect repellantand attractant systems to control insects. For example, in oneembodiment, a system used to attract and destroy insects operates onpropane to lure insects into a trap. In another embodiment, a systemused to repel insects is a misting-type system that uses insecticides toeliminate insects from outdoor environments. In one embodiment, themisting type system employs a source of insecticide from either tanklessor drum-based systems that can be activated by a remote control or seton a timing schedule. In yet another embodiment, a system used to repelinsects is an air curtain that can be employed in residential outdoorliving spaces. In yet another embodiment, an acoustic system is used torepel insects in the air with sound waves. In yet another embodiment, anacoustic system is used to kill mosquito larvae in water. Other moretraditional systems can employ netting used to protect the environmentor candles to repel insects.

Moreover, outdoor living spaces often include equipment requiring fuelsources, such as the propane-based system used to attract insects thatis referenced above. It is known that such systems require that thepropane be replenished or replaced from time-to-time. Similarly,equipment requiring an insect repellant or insecticide is known torequire replenishment or replacement of the active chemical agent fromtime-to-time. An acoustic system deployed in a body of water to killinsect area, may require monitoring of the water level or other watercharacteristics to remain effective.

The present disclosure is directed to systems and methods to replenishor replace the liquid resources, such as fuel, chemicals, or water, onan automated basis, especially for an insect control system.

Through this managed service, and with the help ofprecise local tools and enabling components, commercial businesses canensure precise, wide-area insect repellent delivery that is consistentwith brand standards over time and across locations. A wide range ofenabling components and technologies are disclosed herein for such apest management system.

In one embodiment, there may be an electrical contact that may need tobe made between the package and the device when the package isinstalled. An electrical feature on the package may contact anelectrical feature on the device. If contact is made, the packagecontents may be dispensed. If contact is not made, the package contentsmay not be dispensed and an alert may be sent over the network.

DETAILED DESCRIPTION

Certain aspects of the present disclosure are directed to pest controlsystems, specifically insect control systems. As referenced herein, pestcontrol is directed to systems and methods that are used to regulateand/or manage pests that are harmful to humans. Such pests can includeanimals, insects, and other organisms. The systems and methods describedfor managing pests are particularly directed to managing insects, suchas mosquitos. However, the principles described herein can be applied tomanage and control other pests.

In an aspect, the scent management system provides businesses with amanaged service for precise, wide-area insect repellent deliverydirected at using scent to deliver memorable brand impressions andexceptional customer experiences. By building intelligence intoequipment deployed on customers' premises, and by managing the equipmentusing a global network and a centralized set of software applications,the scent management system provides unprecedented quality and controlof a remotely managed scent service for customers and ensures that scentmanagement services are efficacious, reliable and consistent. Such ascent management system is capable of ensuring a defined level ofquality based on intelligence built into the system, from the diffuserdevice to the centrally managed network operations center (NOC), whichmonitors device performance across all customers and across all devicesfor each customer. The scent management system is capable of deliveringidentical scent impressions across all locations, if so desired, throughmeasured insect repellent output and in-space metering for preciseconcentration. The scent management system provides a managed scentservice that delivers a consistent brand impression through the precise,dynamic control of a network of scent diffusion devices in either aremote or a local fashion. Features of the scent management system, suchas two-way communication with networked scent diffusion devices toreceive data from the devices and to control the devices remotely,coupled with features of the devices, including sensors and/orprogramming to switch between installed packages of insect repellent,enables the scent management system to be deployed as part of multipleservice offerings, including self-service and full-service models ofoperation. In a self-service model, users may select settings for thedevices and receive indications regarding replenishment, such as througha customer application. In a full-service model, settings may beselected and modified by the NOC not just for one location but across asmany locations as required to conform to brand management goals,replenishment alerts may go to the NOC which is then responsible formanaging the replenishment, and the like. Communication with the NOCallows users the confidence that the devices in a space are operating asdesired without having to be hands-on with the devices or with a controlapplication for the device. Of course, the flexibility of the scentmanagement system enables users (such as non-NOC staff) to utilizecontrol applications to monitor and control the scent diffusion devicesas desired. The system enables intelligent, deterministic delegation ofroles, authorities, and permissions across the network of diffusers topreserve brand integrity. Users can control roles, authorities, andpermissions across a hierarchical organization (e.g. parentcompany/corporate, franchise, location) to enable diffusion devicecontrol on a local level, such as on a location basis, or at a corporatelevel, and the like.

The scent management system may be useful not just for scent brandingand delivering consistent scent impressions, but also for odormitigation, odor neutralization, product advertising,aromatherapy/stress reduction, and the like. Other functional benefitswill be described herein.

The scent management system may include one or more diffusion devices.Each diffusion device may contain a processor, such as amicrocontroller, capable of reporting information (telemetry data) aboutdiffuser status via the Internet to one or more Cloud-based businessapplications. The microcontroller may be capable of controlling theunits autonomously, based on control instructions sent by the businessapplications. The business applications store historical data about thediffusion devices, which enables reporting on this data and mining ofthe data in order to improve scent management services. A NOC may beutilized to monitor the health of the end-user diffusion devices, andmay react to alerts by adjusting the settings of the diffusion devices,or by creating a work order (e.g. to roll a truck, e-mail an on-sitecontact, etc.) in order to address a service issue or replenishmentissue. Alternatively, devices may be self-serve, non-NOC managed. Inembodiments, the networked diffusion devices form part of an Internet ofThings.

In an embodiment, the scent management system may include: a diffusiondevice with built-in intelligence enabled by a built-in microcontrollermodule, plus communication abilities enabled by wireless local and widearea network communication modules; and diffusion device networkconfigurations that support the intelligent management of fragrancedispersion, either locally within a repellent-treated environment, orremotely by one or more centralized or distributed network operationscenter(s) (NOCs) staffed by scent system administrators. The scentmanagement system includes business processes enabled by the diffusiondevices, deployed within defined scent dispersion networkconfigurations. Throughout this specification, the terms “scent device”,“scent dispersion device”, “diffuser device”, “diffuser”, “scentdiffusion device”, or “scent diffuser device” may be usedinterchangeably with each other and with the term “diffusion device”,except where context indicates otherwise. It should be understood thatthe use of scented liquids in the diffusion device is exemplary of oneof the kinds of liquids that may be used in the scent management system.Indeed, scent neutralization liquids, disinfectant, repellents,pesticides, fuels, cleansing or other liquids may also be used in thediffusion devices. Throughout this specification, the terms “cartridge”,“package”, and “reservoir” are used interchangeably with each other,except where context indicates otherwise. Various aspects of the scentmanagement system are described herein. Further, it should be understoodthat the devices may work to dispense any liquid, such as in a gas orvapor colloidal mixture. FIG. 1 depicts an exemplary architecture 100for a scent management system. In this embodiment, a master diffusiondevice 102 is in communication with one or more slave diffusion devices104 and a server 108, such as a cloud server running cloud-basedbusiness applications. In this embodiment, the device 102 communicateswith the server 108 to receive control instructions, systems updates,and the like from and to transmit telemetry data and the like to a NOC118. Communication may be through a cellular connection. The devices102, 104 may be in communication with environmental, or have onboard,sensors 110. NOC user devices 114 may communicate through the server 108with the devices 102, 104. A customer control device 120 may be used tocontrol the devices 102, 104 through the server 108. An advertisernetwork user interface 112 may be in communication with the server 108.

In an embodiment, the scent diffusion device may include acartridge-based removable repository for insect repellent or otherliquid to be diffused, and a diffuser that atomizes the insect repellentinto particles to deliver targeted and controllable concentration levelsof the insect repellent or liquid. The particles may be variously sized,such as micro-droplets, or large or small aerosol particles. Inembodiments, the diffuser results in minimal fallout of particles. Thediffuser includes at least one of a micro-droplet generator, anatomizer, a nebulizer, a vaporizer, an evaporative wick, a saturatedsolid, and the like.

In an embodiment, the scent diffusion device may include a solid scentmedium cartridge that heat energy, such as from a coil, light bulb,candle, heated blower, convective heat source, or the like, to heat thescent medium in the cartridge, while a fan blows through the medium todistribute insect repellent. Controlling the insect repellent diffusionremotely may involve controlling at least one of the fan or the heatsource.

In embodiments, such as where a scent diffusion device may include awick or other fixed or solid medium, diffusion rate/efficiency orwicking rate/efficiency may be adjusted over time or periodically, suchas by adjusting an aspect or parameter of the operation of a fan. Forexample, the amount of liquid available for diffusion may decrease overtime as the device operates. In some embodiments, the amount of liquidin the device may decrease at a predictable rate, such as at anexponential rate that can be predicted based on a model, such as aphysical or chemical model. As the amount of available liquid decreasesin the device, it may become more difficult to induce diffusion of theremaining liquid from the device. This may be due in part to changes inan aspect or parameter of a fixed medium that is used to aid diffusionover time. For example, a wick may dry up, a solid insect repellent cakemay dehydrate, or the like. By controlling a parameter of a device thatis used to promote diffusion, such as the speed of a fan, adjustmentsmay be made to address changes in diffusion characteristics. Forexample, the fan speed in the diffusion device throughout its operationmay be adjusted such that it runs slower when a new cartridge of liquidor other fixed medium is placed in the device, and as a result, the wickor other fixed medium may dry out more slowly. Then, as the deviceoperates and the characteristics of the wick or other solid mediumchange, the fan may be sped up to obtain a relatively consistent levelof diffusion of the liquid from the cartridge or other fixed medium. Insome embodiments, the operation of the fan may approximate an elliptoidcurve, an exponential curve, or other function suitable to obtain acontinuous level of diffusion of the liquid. In embodiments, such aswhere the liquid is an insect repellent, controlling the fan to obtain acontinuous level of diffusion of the insect repellent may result in asubstantially stable intensity of insect repellent over time.

In an embodiment, a piezoelectric device may be used in the scentdiffusion device to cause a vibration in the package, such as viaultrasonic surface wave effects, or through the use of microscopicallyperforated vibrating mesh (VMT). Such vibration may cause an oscillatingmotion and pressure in the liquid within the package and effectatomization of the liquid. The piezoelectric device may be remotelymanaged to control insect repellent levels.

Other devices may be used in the system for scent diffusion, such asthose including atomizers with hydraulic spray nozzles, liquid-liquidimpinging atomizers, air-liquid impinging atomizers, airblast atomizers,prefilming atomizers, high voltage electrospray, and the like.

The diffusion device may further include a pump, to enable the venturieffect or otherwise draw the liquid from within the package to enablediffusion, with a controllable duty cycle. The diffusion device mayinclude a fan that aids in distributing the particles. The fan may below noise, such as by use of a low-noise fan or noise cancellingtechnology. The diffusion device enables uniform dispersion of vaporizedinsect repellent throughout an environment using dispersion technologiesthat require minimal heat. Such technologies allow insect repellentintegrity to be sustained over time.

In some embodiments, the pump may be a conventional air pump or a speedcontrol air pump. With a conventional air pump, the amount of scentoutput may be controlled using a duty cycle, such as, for example, aduty cycle of “on” for 2 minutes and “off” for 4 minutes to provide a33% duty cycle. Given the ability to remotely control pump operation innetworked scent diffusion devices, the voltage driving the pump may beincreased or decreased remotely, such as in a range of roughly +/−20%from a 10V standard, or from 8 V to 12 V. Controlling the voltagedriving the pump enables remote control of the diffusion rate of thedevice, independent of the voltage range and independent of duty cycle.At a given duty cycle, output can be attenuated or augmented by simplyaltering the voltage for the pump. For example, for multiple diffusersdeployed in an environment, assuming that all of the diffusers are setwith the same duty cycle, the voltage driving diffusers deployed insmaller spaces of the environment may be lowered to attenuate outputwhile the voltage driving diffusers deployed in larger spaces of theenvironment may be raised to augment output. In this example, a dutycycle including an “on” portion of 1 minute at a low speed setting mightput out X micrograms per hour, while the same duty cycle portion of “on”for 1 minute at a high speed setting may put out 3.times. micrograms perhour. Voltage control of the pump enables volumetric control of thedevice running on a continuous or nearly continuous basis.

Referring now to FIG. 22, an embodiment of a diffusion device isdepicted. In this view, the housing 2202 contains a pump assembly 2204that pumps liquid up out of the reservoir(s) through tubes attached tothe pump and assembled into fittings 2212. One or more valves, such assolenoid valves 2208, 2210, are placed in line in the tubes to turnpumping on and off.

The diffusion device may include a programmable microcontroller modulewith a memory (fixed or removable) for controlling device functionality,such as control of volume, duty cycle, schedule settings, and the like.The diffusion device may include a wireless local area network modulecapable of communicating with other devices within a physical locationvia radio frequency communications including IEEE standards (such as,WiFi, Zigbee, Bluetooth, etc.) Communications protocols that may be usedby the diffusion device include one or more of Zigbee, MiFi, MiWi, DMX,ANT, Z-Wave, Insteon, JenNet-IP, X10, mesh network, visible light,ultrasound, infrared light, IP version 6 (IPv6), such as IPv6 over LowPower Wireless Personal Area Networks (6LoWPAN), and the NeighborhoodExchange Protocol. The diffusion devices may form a machine-to-machinenetwork. The diffusion device may include a removable wireless wide areanetwork (WWAN) module capable of electronic communications with one ormore remote Network Operations Center(s) via, for example, atelecommunication cellular network. References to a “Network OperationsCenter” or “NOC” throughout this disclosure should be understood toencompass a single, centralized center, or a set of multiple distributedcenters. In embodiments, the diffusion device may include communicationstechnology for wired installations. Telemetry data, such asrepellent-level replenishment alert, may be delivered over thecommunications network. Device firmware may be upgradable via thenetwork.

In an embodiment, on the motherboard of the device, connectors may beadapted to configure the communications module readily or to render thecommunications module modular, such that it may be swapped in and outreadily. For example, the device may be manufactured such that at adistributor, retailer, customer, or other downstream site, acommunications module may be installed or swapped. For example, thedevice may be shipped from the manufacturer to the distributor with acellular communications module installed, but upon receipt, a need forWiFi- and Bluetooth-enabled devices may emerge. The distributor may beable to open the devices and swap out the cellular communications modulefor the WiFi-enabled and/or Bluetooth-enabled module. In some examples,the devices may be able to accommodate a plurality of communicationsprotocols such that in this example, the distributor need only to add inthe WiFi and Bluetooth modules to the existing cellular module. In otherembodiments, the communications module may be embodied with firmware,such that capabilities may be modified by a firmware update, such asdelivered over a cellular network via a cellular networkingcommunications protocol, over the Internet or other IP-based network, orthe like. In embodiments the communications module may be embodied in ormay use a field programmable gate array (FPGA), such that it may bere-programmed in the field to meet changing requirements.

On-board sensors may alsowork as an anti-tampering mechanism if contact with the sensors is lostwhile power is still sensed or utilized by the device.

The package for the diffusion device may include physical features foranti-tampering that prevent the package from operating properly in adevice not configured to accept the package. For example, the packagemay include an RFID tag 1208 for identification and the RFID tag must beread correctly or the diffusion device will not function. Reading theRFID tag may be done on-board the device by an integrated RFID reader ormay be done with a separate RFID reader, such as upon installation ofthe package or during a routine inspection. In another example, thepackage may include another identification tag, such as a bar code 1204or QR code 1202, which may be imaged by on-board imaging or a separateimager. The images may be transmitted to the NOC for analysis andapproval or storage.

In an embodiment, an atomizing diffusion device may include at least twopackages with liquid disposed in the diffusion device, an anti-tamperingidentifier associated with at least one of the packages, and aprocessor, operatively coupled to the scent diffusion device, thatdetermines a tampering indication based on the anti-tampering identifierand causes a switch between the packages based on the tamperingindication.

In an embodiment, the diffusion device may include a chemical sensor influid communication with the package for detecting the presence of aspecific component in a liquid, such as one disposed within the package.The specific component may be a tracer or tag molecule placed in thepackage, so that when the tag or tracer is detected, the package isauthenticated. Conversely, if the tag or tracer is absent, the packagemay be identified as potentially fraudulent. In embodiments the chemicalsensor may be disposed outside the package, but may be in fluidcommunication with the contents of the package in order to sample theliquid of the package to determine the presence or absence of thespecific tag or tracer component. If the chemical sensor detects thespecific component, and thus authenticates the package, the device mayproceed to operate to diffuse the liquid as described herein. If thespecific component is not detected, various actions may be taken. Forexample, a visual or audible signal may be generated, such as a flashinglight (e.g., an LED) or a beeping sound, or any other visual, auditory,tactile, or other sensor cue that would alert a user or observer of apotential problem, such as cues of various types known to those ofordinary skill in the art. Such a signal may indicate the absence of thespecific component, which may be due to tampering, an incorrect package,a depleted package, an error, or the like. In other embodiments, thesignal take the form of a message, alert, or communication that istransmitted over a network, such as to a central location, anindividual, a manager, a computer, a mobile device, and the like. Incertain embodiments, the chemical sensor may sample the air for thespecific component, and when the component is not present in the air,the sensor may send an instruction over the network to the diffusiondevice to cease operation.

In embodiments, the package may be embodied in a cartridge, a reservoir,a bag, a balloon, a membrane, and the like. Referring to FIG. 4, acartridge for a scent management system includes a liquid reservoir 404and an atomizer head assembly 402, wherein the liquid reservoir ispositioned below the atomizer head. The liquid reservoir has asubstantially cup shaped geometry, and its top edge is joined to theatomizer head assembly, such as by an ultrasonic weld, a twist lock withO-ring seal, or the like. A conduit or tube 408 for the transportationof the liquid in the reservoir is joined to the atomizer head on itsfirst end, and the second end of the tube extends into the liquid 410within the reservoir, preferably extending sufficiently below thesurface of the liquid to maximize the total volume of liquid drawn fromwithin the reservoir as the liquid within the cartridge is depleted.There may be some condensation, but mostly the excess liquid stays instate and drops back into the reservoir.

The atomizer head may have a gas (e.g. air) inlet passage 412 having oneend in fluid communication with a compressed air source. The second endof the gas inlet passage may be in fluid communication with an orificeplate 418 containing a flow restriction orifice 420. In certainembodiments, a venturi may be used in place of an orifice plate. Theorifice plate separates the gas inlet passage from a mixing chamber 422.The mixing chamber may have a wall opposite the orifice plate, theopposing wall having an atomizing orifice 422. Another wall of themixing chamber may have an opening 424 in fluid communication with thetube. The atomizing orifice may be in fluid communication with anexpansion chamber 428. The expansion chamber may be in fluidcommunication with a baffle chamber 430. The baffle chamber may have anoutlet 432 to the surrounding environment to be treated with theatomized liquid.

The operation of the atomizer head may be as follows: Compressed gasflows into the gas inlet passage, through the orifice plate's flowrestriction orifice, and into the mixing chamber. This creates arelatively high-pressure region on the gas inlet passage side of therestrictor orifice, and the gas flow velocity out from the restrictororifice increases and generates a relatively low pressure region on themixing chamber end of the restrictor orifice. The relative low pressuredraws liquid from the reservoir into the mixing chamber through thetube, and the liquid joins the flow path of the gas out of therestrictor orifice creating a mixture of gas and liquid. The gas liquidmixture then passes through the atomizing orifice into the expansionchamber, creating an atomized mixture of liquid and gas. The atomizedmixture of liquid and gas flows into the baffle chamber, and theatomized liquid and gas flows through the outlet into the surroundingenvironment to be treated.

As the atomized mixture of liquid and gas flow though the expansionchamber and baffle chamber, it impinges on the surfaces of the chambersand walls separating the chambers. This results in the removal of asubstantial portion of the larger particles of atomized liquid from theatomized liquid and gas mixture. The larger particles condense back intoliquid and drain back into the reservoir through a weep hole in thepartition between the expansion chamber and the reservoir. Also, anyliquid not completely atomized after the gas and liquid pass through theatomizing orifice drains back into the reservoir through the weep hole.The baffle chamber also acts as a sound level suppressor, muffling thesound of the gas and atomized liquid flow through the atomizer headassembly. The cartridge is inserted into a diffusion device, with thecompressed gas inlet passage coupling with an air fitting 414 to providethe supply of compressed gas to the cartridge.

The package may be used in the diffusion devices described herein butalso in other scent diffusion devices, such as devices that plug into awall outlet.

In an aspect, a package for use with a scent diffusion device mayinclude a reservoir that holds a liquid and an atomizer head assembly,wherein the reservoir is joined to the atomizer head assembly at a topedge of the reservoir and a tube for the transportation of the liquid inthe reservoir, wherein the tube is joined to the atomizer head assemblyon a first end while a second end of the tube extends below the surfaceof the liquid. A gas inlet passage of the atomizer head assembly mayhave one end in fluid communication with a compressed air source and asecond end of the gas inlet passage in fluid communication with anorifice plate comprising a flow restriction orifice. A mixing chamber ofthe atomizer head assembly may be separated from the gas inlet passageby the orifice plate, the mixing chamber having a first wall oppositethe orifice plate comprising an atomizing orifice and a second wallcomprising an opening in fluid communication with the tube. An expansionchamber may be in fluid communication with the atomizing orifice and abaffle chamber, the baffle chamber having an outlet to a surroundingenvironment. A gas flowing into the gas inlet passage through the flowrestriction orifice generates a relatively low pressure region in themixing chamber that causes liquid from the reservoir to be drawn intothe mixing chamber through the tube where it joins the flow path of thegas out of the restrictor orifice creating a mixture of gas and liquidwhich then becomes atomized when it passes through the atomizingorifice. The liquid reservoir may have a substantially cup shapedgeometry. The top edge of the reservoir may be joined to the atomizerhead assembly by one of an ultrasonic weld and a twist lock with O-ringseal.

In embodiments, certain diffusion devices may be capable of dispersingmultiple insect repellents or other liquids. In embodiments, thenetworked scent diffusion device may include the capability to acceptmultiple packages (also known as cartridges or reservoirs) for operationin multiple configurations. The diffusion device may be able to accept aplurality of packages, such as greater than one package. In one example,the diffusion device has two packages. When one package is depleted ornear depletion, the diffusion device may switch to diffusion from thesecond package. In another example, the diffusion device can accept fourpackages, where two packages house a first scent and the other twopackages house a second scent, so that both the first scent and thesecond scent each have backup packages and the diffusion device canautomatically switch to a new package when one becomes empty or is neardepletion. In embodiments, the combined volume of liquid in the packagesinstalled in the device may be greater than a percentage of the expecteduse in a replenishment service cycle. For example, the combined volumeof liquid may be more than 50% of the expected use in a service cycle.Switching between packages may be done upon sensing when a package isdepleted or near depletion or may be done on some other basis, such asafter an elapsed time, if it is day or night, upon detection of acondition, upon detection of a user, and the like. A switching system isdescribed elsewhere herein.

In another example, the diffusion device may operate with multipleinsect repellent packages, and each package may house a different noteof a fragrance chord, wherein the diffusion device may be programmed toblend the notes to form the fragrance chord. In embodiments, thefragrance chord may be a particular combination of “base,” “mid-” and/or“high” notes. The fragrance chord may be specified by a brand/mediacampaign specification.

In order to maintain consistent insect repellent in an environment whereinsect repellent in a reservoir may experience some evaporation ordepletion, certain methods may be employed. Insect repellent is amixture of numerous liquids, each with different partial pressures. Whenusing atomization, components with higher vapor pressures will flash offearlier, and the heavier components will recycle back into the oilreservoir. The net effect is that as the insect repellent depletes thefragrance chord, or resultant fragrance, will actually change. Onemethod to potentially influence this effect is to shift the duty cycleof the diffuser device (e.g. increase the t in the duty cycle) as theoil level depletes. Knowing the liquid level, either through sensors,direct measurement or estimation, enables applying the correctionfactor, t, to preserve the fragrance chord. Another method may involveleveraging a second cartridge. In this scenario, if the main cartridgeis partially depleted, adding a small amount of the fragrance oilcontained in the second cartridge will add top notes back to thefragrance chord.

In an embodiment, as scent oil is depleted over time in a package of adiffuser device with a scent oil recycling feature, the average size ofthe molecules in the remaining scent oil increases. One statisticalexplanation is that larger molecules of scent oil are more likely tofall back into the package through the recycling feature duringatomization. This change in average molecule size may affect theperformance of the diffuser and may result in a lower rate of scentdiffusion for a fixed duty cycle setting. A process for adjusting theduty cycle of the diffuser device to compensate for this change inaverage molecule size and reduced rate of diffusion may includeincreasing the duty cycle, pump pressure or other diffuser setting whichaffects rate of diffusion. In one embodiment, a liquid level sensor ofthe diffusion device may determine the liquid level remaining in thepackage and a processor of the diffusion device may use the sensedliquid level to modify a diffuser setting as described herein in orderto maintain a desired rate of scent diffusion, a target value of ascent, or a brand management goal. A method may include receiving asensed liquid level in a package of a scent diffusion device, whereinnon-atomized scent oil is recycled back into the package during deviceoperation and adjusting the duty cycle of the diffusion device tomaintain a desired rate of scent diffusion. Adjusting may include atleast one of increasing the duty cycle, increasing the pump pressure,and changing a diffuser setting.

In another example, the diffusion device may be capable of acceptingmultiple packages, and switching between the packages is done inaccordance with a time, such as to deliver a day and a night insectrepellent. In yet another example, the diffusion device is capable ofaccepting a plurality of packages, wherein one package includes a scentneutralizer and one or more other packages includes an insect repellent,such as the diffusion device can switch to the scent neutralizer asneeded or in between dispersion of different insect repellents. In yetanother example, the diffusion device may house multiple packages andthe desired package may be selected remotely. For example, duringdaytime hours when certain species of insect are more active, they maychoose to diffuse a particular insect repellent which is effectiveagainst those daytime species in the outdoor common areas of the hotel,such as the hotel entrance, outdoor pool/spa, or outdoor dining areas.The fragrance diffusion may be triggered remotely. Continuing with theexample, during nighttime hours, the scent management system may causethe diffusion of a second insect repellent which is effective againstcertain insect species that are more prevalent during nighttime hours.Such cartridge switching might be remotely scheduled by day-part in thescent management system, or may be triggered locally by an environmentalsensor such as photo-electronic device capable of measuring the currentambient light level. Other sensors which might control diffusion fromone or more insect repellent cartridges include outdoor weather sensorspresenting ambient temperature, wind speed or direction. Similarly, suchweather data may be provided from a remote data service providingsimilar information. In yet another example, the diffusion device mayhouse multiple packages and the liquids in the packages may be blendedprior to diffusion.

In still another example, one of the packages could be a diluent toreconstitute a concentrated fragrance oil, and the blending could bedone at the level of the diffuser. Blending may be programmed to producea scent concentration factor specified to adjust for daily or seasonalvariations in local insect populations. In this example, a plurality ofconcentrated insect repellents may be available in the diffusion device(such as in a carousel), and one or more of the plurality of repellentscan be selected for diffusion.

In a further example, the diffusion device may accept a single usepackage of insect repellent, either in addition to the existing dualpackage configuration or instead of it. For example, a guest in a hotelmay be offered various single use packages of fragrance for selection ina lobby that they can install themselves into a diffusion device. Instill a further example, the scent in the package may be provided by acrystal, a powder, or another non-liquid element that is reconstitutedor diluted prior to diffusion.

In embodiments, the insect repellent used by the diffusion devices maymatch scents to be used in passive scent devices, such as candles,tarts, or gels. The fragrance may be delivered as an oil or as a solid,such as a solid crystal.

Switching between packages may be done using an automated switchingsystem. An automated switching system for a networked scent diffusiondevice housing a plurality of insect repellent packages enables a switchbetween packages upon meeting a condition. For example, the conditioncan be the determination that a level of a repellent in a package islow. In another example, the switch may be done after an elapsed time ina programmed switchover to mitigate scent desensitization. Inembodiments, the device may utilize a FIFO replenishment process.

In embodiments, the switching system employs a valve. In embodiments,the switching system employs a liquid level sensor, such as anelectrical (e.g. conductive, capacitive transmitters to measure thecumulative capacitance which is a function of the amount of liquid andis based on the liquid's dielectric constant, resistive), magnetic (e.g.Hall effect sensor or Hall effect switch), mechanical (e.g. liquid levelfloat that triggers a switch, physical switch, strain gauge), optical(e.g. imaging sensor, liquid level float plus imaging sensor) liquidlevel sensor, hydrostatic sensors (e.g. displacers, bubblers,differential pressure transmitter) to measure the pressure of theliquid, load cells to measure the mass in the package, electromagnetictransceivers that transmit an EM signal at the surface of the liquidwhich reflects back to its receiver with a time delay that is used tocalculate the liquid level (EM could be ultrasonic, laser, radar, etc.depending on the wavelength of the EM signal that is sent and received),or any other liquid level sensor. In one embodiment, the liquid levelsensor may include a floating magnet disposed within a track inside thepackage, wherein as the liquid level changes, the floating magnet movesinside the track. At least one Hall effect sensor or Hall effect switchis disposed outside the package, wherein the Hall effect sensor or Halleffect switch is disposed in such a way as to sense the position of themagnet. In an embodiment, when a particular position of the magnet issensed, which may correspond with a predetermined liquid level, a switchmay be activated that causes a move from a first state of the switch toa second state of the switch. The switch may be used to switch thediffusion device's utilization of one package to utilization of anotherpackage. For example, the switch may be a solenoid switch betweenpackages. In another embodiment, data from the liquid level sensor maybe used to monitor liquid levels inside the one or more packages in thediffusion device and predict when the package(s) will be depleted ofliquid. This prediction may be used in scheduling replenishment servicesso that the diffusion device is never out of liquid. The NOC, a localcontroller, a gateway device, or any of the devices may perform a daysof supply calculation using an algorithm as part of a predictive modelto determine when packages in a device will be depleted. The algorithmmay utilize measured current liquid level and divide that by the averageusage rate per day to determine a number of days of supply remaining.The average usage rate per day may be defined for any time perioddesired. The result of the calculation may be used to schedule an event,such as a just-in-time replacement of a package, the dispatch of areplenishment technician, or the transmission of an alert/email toon-site personnel. The days of supply calculation may also be done usingan estimated liquid level in place of the measured liquid level, whereinthe estimate may be determined based on a duty cycle used by the device,optionally in combination with other historical or modeled dataregarding device operation. The days of supply calculation may alsoutilize information such as a duration of operation, a compressed gasusage, and the like in place of the measured liquid level in order toestimate an amount of liquid remaining. In an embodiment, the liquidlevel sensor for a networked scent diffusion device provides real-timefragrance levels and causes an alert or signal to be generated when thereading from the liquid level sensor indicates a need for replacement ofa package, when an unexpected reading is obtained, and the like. Inresponse to receiving the unexpected reading, a control instruction maybe sent to the device to turn it off or otherwise cease diffusionoperations. If the reading is higher than expected, which may besuggestive of a clog, a control instruction may be sent to the device toswitch to a new package. Alerts or signals in this example andthroughout this specification may be one or more of visual, audio,electronic (e.g. SMS/MMS, text, email, pop-up, etc.), and the like.Throughout this specification, alerts may be sent asynchronously whenthe device reports an event, or if a device stops reporting to the NOCfor a predetermined period. Throughout this specification, an alert maybe triggered whenever a device goes from a non-alert state to an alertedstate. If two of the same alerts are reported in a row, the second alertwill not cause the device to retrigger a new alert—instead it willconsider the alarm still set. Audio alerts may be transmitted through aspeaker of the diffusion device. Visual alerts may be transmittedthrough LED lights of the devices, or the like. In another example,based on the data on the duty cycle and the SCF, a predictive algorithmmay be used to estimate the actual liquid level. A single sensor near anempty level of the reservoir may be used to verify liquid level.

In an aspect, an atomizing diffusion device may include a floatingmagnet disposed within a track inside at least one package with liquidfor the diffusion device, wherein as a liquid level inside the packagechanges, the floating magnet moves substantially vertically along thetrack. The device may further include at least one Hall effect sensor orHall effect switch disposed outside the liquid at a position to enablesensing the position of the floating magnet in the track. The device mayalso include a processor, operatively coupled to the Hall effect sensoror Hall effect switch, for generating a signal indicative of the sensedposition of the floating magnet and a control instruction for a switchbased on the signal and a switch, operatively coupled to the processor,that receives the control instruction from the processor, wherein thecontrol instruction causes the diffusion device to switch from utilizingone package in the diffusion device to utilizing a different package inthe diffusion device. The switch may be a solenoid switch. The device ofclaim may further include a scheduling facility that receives the signaland predicts when the package will be depleted of liquid or determines apackage replenishment schedule. The device may further include a remotecomputer in communication with the processor for receiving the signaland generating an alert if the signal indicates a need for replacementof a package or when an unexpected signal is obtained. The processor maybe adapted to send a signal indicating the switch to the differentpackage in the diffusion device.

In embodiments, the switching system employs a sensor that measures thepressure in the package to determine the presence of a vacuum or athreshold pressure/partial pressure. Certain pressure readings may beassociated with a liquid level in the package. When a certainpredetermined pressure reading is obtained, it may cause an alert orsignal to be generated indicating a need for replacement of a package,an unexpected reading, and the like.

In embodiments, the switching system employs a camera or other imagingfacility to monitor the liquid level inside the package. For example,the package may have a transparent portion that may allow a camera toimage the liquid level. When the camera determines that the liquid levelhas dropped to a certain point, an alert or signal to be generatedindicating a need for replacement of a package, an unexpected reading,and the like.

In one embodiment, this may be accomplished in thefollowing manner: 1) the scent gateway device is installed and pluggedinto AC or DC power; 2) a startup protocol within the scent gatewaydevice includes a self-diagnostic, followed by activation of the WWANmodule, and the establishment of communications with the NOC; 3) thescent gateway device then receives configuration settings from the NOC,and begins dispersing scent according to its downloaded programming; 4)upon establishing its own configuration, the scent gateway devicesearches its wireless local area network for scent node devices; 5) uponidentifying scent node devices, the scent gateway device thenestablishes communications with each scent node device; 6) the scentgateway device gathers information from each scent node device, and thenrelays that information to the NOC; 7) the NOC receives the deviceinformation and communicates program settings and information to eachscent node device, via the scent gateway device; 8) each scent nodedevice, having received its configuration settings from the NOC via thescent gateway device, begins dispersing scent according to itsdownloaded programming. This exemplary scenario provides remote andcentralized management of a scent dispersion network via a scent gatewaydevice, which is a scent dispersion device that also acts as the networkgateway. Communication between devices may occur via various networkingprotocols listed elsewhere herein, such as Bluetooth (full power andLE), MiWi, Zigbee, and the like. In embodiments, for a large area,multiple gateway devices may be deployed to establish one or more scentdispersion networks in a location.

Once a scent dispersion network is established, the scent gateway devicemay continue to communicate and store data and instructions to and fromeach paired or associated scent dispersion device within a venue, andthen relays the data and instructions between the NOC and each scentdispersion device. In this manner, the status of the scent dispersionnetwork and each device is regularly communicated to the NOC, and NOCadministrators are able to remotely monitor scent dispersion networkoperations, and control the devices to take actions to ensure insectrepellent dispersion is conforming to commercial or regulatory standardsor other parameters. In one embodiment, the scent dispersion networkincludes only a scent gateway device in communication with a NOC and noassociated or networked scent node devices.

The NOC may include a database of all diffusion devices in the field,including information such as device type, location, customer, sensorreadings from the diffusion device, a scent diffusion level, insectrepellent oil volume, insect repellent type, package/reservoir type,compressed air volume, number of devices in a local network, an on/offstatus, any alerts, current firmware, permissions and security settings,and the like. Any of the device settings or statuses may be viewedand/or or controlled remotely by a NOC user. The NOC enables runningreports in order to check system health and effectiveness at customerlocations and generating alerts when diffusion device issues aredetected at customer sites. The NOC enables managing cellular wirelessprovisioning, accounts, usage; remotely managing local mesh wirelessnetworks used to interconnect diffusion devices at a customer site;managing firmware updates in the field; utilizing centralized softwareapplications to gather telemetry data from diffusion devices over theInternet; and the like. A ticketing and workflow facility, describedelsewhere herein, for fired alerts may allow NOC users to log responsesto the alerts and route tickets to people who can resolve them (e.g.,service techs). FIG. 2 depicts an embodiment of a scent managementsystem 200 that enables remote control, monitoring and management ofscent devices from a central NOC. In this embodiment, enterpriseapplications 202 for workflow, analytics, and support as well asconsumer apps 204 for mobile and web control may interface with the NOCsoftware 208, which may run in the NOC 118. The enterprise application202 may run on a NOC user device 114. The consumer apps, such as acustomer control app, may run on a consumer control device 120. The NOCsoftware 208 may include features such as virtualized device services,web service APIs, a real-time alert engine, distributed data storage,data rate services, account management, a firmware upgrade manager,secure networks and date, and a scalable cloud architecture. In thisembodiment, the NOC 208 communicates via WiFi or a cellular internetgateway with diffusion devices 210 which themselves may be locallynetworked, such as Zigbee networked. FIG. 3 depicts an embodiment ofenterprise architecture 300. In this embodiment, the architecture 300includes a billing & financials facility 302 that receives billing &payables data from a device management facility 308, an inventorymanagement facility 304 that interfaces with the device managementfacility 308 for the purposes of exchanging information on new devices,repairs, and replacements, a NOC 118 for monitoring diffusers 102, 104through the device management facility 308, a ticketing & workflowfacility 310 that interfaces with the NOC 118, the device managementfacility 308, and the service tech interface 314 for creating andmanaging tickets for service staff, a customer interface 312 for viewingdiffuser status and adjusting settings, and a service technicianinterface 314 to receive service requests and update status, install andservice diffusers.

For example, system administrators in the NOC are able to, among otherthings, review status data received from devices within the scentdispersion network, control the program settings of all networked scentdevices, identify performance problems within scent dispersion networks,schedule the replenishment of fragrance cartridges, and schedule themaintenance, repair or replacement of malfunctioning networked scentdevices. The NOC administrators are able to accomplish such tasksmanually by reviewing status data and making changes in real time, or byallowing the NOC software to automatically take action to maintain andsupport scent dispersion network based on pre-established rules andheuristics. FIG. 6 depicts an exemplary embodiment of a NOC system view600. In this view, tabs are visible for alerts, devices, information,users, and a search window. An installation sites window lists sites byparent company (e.g. Hotel A, Hotel B, Hotel C), sites that aresubsidiary or otherwise associated with the parent (e.g. Hotel A1, HotelA2), and yet further sites associated the secondary level of the companyhierarchy (e.g. Hotel A1-Location 1, Hotel A1-Location 2, HotelA1-Location 3). In this figure, the user tab is exposed indicating whois a contact point for the installation. FIG. 7 depicts an exemplaryembodiment of an overview 700 of diffusion devices at a particularlocation. In this example, the diffusers are listed, a map with alocation of the sites is shown, alerts are shown, and any NOC-specificfunctions, such as adding a diffuser or gateway, may be shown. For thediffuser listing, information such as a current setting, a currentinsect repellent level, a WiMi signal strength, and a device type may beshown along with any other diffuser or sensor data. Each diffuser may beselected so that the user can drill down on specifics for that diffuser.FIG. 8 depicts an exemplary embodiment of a view of a “drill down” 800to diffusion device data. Current insect repellent level, currentsetting, a schedule, a repellent level/RCL (repellent concentrationlevel)/SCF (scent concentration factor) history, and a temperaturehistory may be shown as well as any other diffuser or sensor data.

In an embodiment, a user interface for a network of scent diffusiondevices may include a device management & monitoring (DM&M) facilitythat includes configurable dashboards to enable a plurality ofactivities for the network of scent diffusion devices, and a securityfacility to set one or more permissions for the activities. Theactivities may be at least one of viewing diffusion device telemetrydata, maps of diffusion device locations, receiving liquid levelreadings or other gauge/sensor readings, providing control instructionsto diffusion devices, reviewing status of and managing scent operationsfor one or more networks of scent diffusion devices, receiving data andstatus information from devices, generating and viewing reports,adjusting device settings, viewing historical graphs showing theperformance of the devices, receiving alerts, configuring alerttriggers, viewing and editing schedules and scent profiles, viewingunitless parameters for articulating and displaying an insect repellentlevel, reviewing alerts to replace packages, ordering and paying for newpackages, renewing subscriptions for scent management services,reviewing system health (e.g. machine down alerts), changing permissionsfor a user, initiating a ticket/workflow, assigning a servicetechnician, adding or removing a device from a network, and adding acustomer/division/store. A mobile application may be used to access theuser interface. The user interface may further include a schedulingfacility to indicate when a service is scheduled to occur in anenvironment and allowing a user to select a scent to be diffused in theenvironment that complements the scheduled service. The alerts may bebased on various criteria and configurable conditions (e.g., low liquid,machine down, etc.). Viewing and editing schedules and scent profilesmay be done for one or more diffusion devices independently of oneanother. Adjusting device settings may involve the user increasing ordecreasing the overall output of all diffusion devices in the locationand allowing a NOC to calculate and adjust the settings for eachdiffusion device needed to achieve the overall location volume setting.

In an aspect, a method of managing scent in an environment may includedisposing one or more scent diffusion devices within an environment,wherein the scent diffusion devices comprise a communications facilitythat enables transmitting signals to and receiving signals from a remotecomputer, receiving at least one scent parameter for scenting anenvironment at the remote computer, and controlling, via the remotecomputer, at least one of the scent diffusion devices to achieve thescent parameter. Controlling may include adjusting an operationparameter of the scent diffusion device in response to a sensed insectrepellent level in the environment.

Referring to FIG. 9, a method for operating atomizing diffusion deviceswithin an environment may include receiving at a computer, liquid leveldata from a plurality of remote atomizing diffusion devices wherein eachdiffusion device comprises a communications facility that enablestransmitting signals to and receiving signals from a remote computer andat least one liquid level sensor, and based on the liquid level data902, creating, via the remote computer, an electronic data structurecharacterizing the transformation of the remote diffusion devices,wherein the electronic data structure includes data specifying at leastone of the production of insect repellent, the procurement of insectrepellent, the management of insect repellent inventory, the delivery ofinsect repellent inventory 904, and causing the remote atomizingdiffusion devices to implement the transformation 908.

In another aspect, a method of managing scent in an environment mayinclude disposing one or more scent diffusion devices within anenvironment, wherein the scent diffusion devices include acommunications facility that enables transmitting signals to andreceiving signals from a remote computer. The method may further includedisposing at least one sensor within the environment that transmitssensor data to the remote computer and receiving at least one scentparameter for scenting the environment at the remote computer. Themethod further includes controlling, via the remote computer, diffusionof a liquid from a source of the liquid that is in fluid communicationwith at least one of the scent diffusion devices to achieve the scentparameter. In embodiments, it is not diffusion of a liquid but diffusionof a gas. Controlling may include setting or adjusting an operationparameter of the scent diffusion device in response to the sensor data.The sensor data may relate to static parameters or dynamic parameters,such as room volume, room geometry, room area, airflow, presence ofodor-producing materials, presence of odor-sinking factors, lighting,air flow, altitude, traffic flow, occupancy detection (e.g. IR, camera,CO2 sensor), proximity sensing, detected odor, insect repellent level,scent concentration factor, temperature, humidity, time of day, season,weather event, detection of a VIP/specific individual entering thespace, such as via a smartphone ping, and the like. In certainembodiments, the scent diffusion device(s) may be configured atinstallation to a baseline configuration, based on the static parametersof the installation site. Then, the device would intelligently adjustoutput of scent, based on algorithms that adjust for dynamic parametersor time-changing conditions. Certain static parameters include roomvolume, room geometry, room area, and altitude. With respect to roomvolume, volume calculations may be performed based on measurements takenof the room, for example, using a tape measure or a laser distancemeter, and then adding the volume data into a data structure whichcharacterizes the space in which the diffuser is deployed. This may bedone at device installation to establish the baseline settings for theScent Concentration Factor. With respect to room geometry, geometry maybe determined by taking into account entries, exits and other areas ofpeople movement, as well as from floor plans. Room area may becalculated based on sensor measurements of linear distance betweenwalls. With respect to altitude, the diffusion devices may have aproximity detection capability based on cell phone technology, whichallows the device to “know” where it is located, for example at aspecific longitude and latitude. Given the long-lat information, thenetworked device can inquire from a remote database the specificaltitude of the location where it is located. This altitude informationis then used to adjust device performance, so for example, a lowersetting of scent diffusion would be used at high elevations with“thinner” air, while a higher level of scent diffusion would be used atlower elevations with “thicker” air.

Dynamic parameters include the presence of odor-producing materials,presence of odor-sinking factors, lighting, air flow, traffic flow,occupancy detection (e.g. IR, camera, CO2 sensor), proximity sensing,detected odor, insect repellent level, scent concentration factor,temperature, humidity, time of day, season, weather event, detection ofa VIP/specific individual entering the space, and the like.

With respect to airflow, a sensor technology may measure the mass of airflowing through a device (typically a tube) per unit time. The airflowsensor may be a flow or pressure differential sensor, or switch, ortransducer. For a fixed airflow HVAC system, the air flow sensor may bein the form of a switch, which indicates whether air flow is occurringor not, above a certain threshold. That information would be used toturn “on” the scent diffuser when air is flowing, and turn “off” thescent diffuser when air is not flowing. For a variable airflow HVACsystem, the airflow sensor may provide an analog voltage reading, whichindicates the actual level of air flow. This analog signal may be usedto automatically adjust the diffuser output, based on the level of airflow. In such a way, the device is able to increase scent diffusion whenair flow is high and lower it when air flow is low (or stop when airflow is “off”).

With respect to the presence of odor-producing materials, semiconductorsensors may identify air born scent particles, wherein such sensors maybe “tuned” to specific scents. The receptors of these sensors may beable to identify the shape of a scent molecule, or alternatively, are“tuned” to a certain quantum effect of the scent molecules such as itslevel of vibration. Based on the detection of certain known malodorswithin an environment, the diffusion device can change its level orscent or conversely can add a secondary odor remediation orneutralization diffusion which counteracts the malodor. In the case ofthe two-cartridge system, one cartridge contains the desired insectrepellent, while the second cartridge contains the odorremediate/neutralizer, which would be diffused according to apre-programmed response, once a certain malodor is detected.

With respect to the presence of odor-sinking factors, certain types ofmolecules will interact with or bind to scent particles, causing them todrop out of circulation. These odor-sinking factors can be identified inmuch the same way as previously described for malodors, allowing thediffusion device to follow a pre-programmed algorithm in response to thepresence of the odor sinking factor.

With respect to lighting, photodetectors are devices that can sense thepresence of photons. There are a variety of well-known and commerciallyavailable technologies which enable photo-detection, and some which alsoare “tuned” to detect and measure the relative amount of certain typesof photons, which have characteristic wavelengths (red, blue, etc. inthe visible spectrum of lights). The diffusion device has data inputsthat enable it to respond to the detection or absence of light, such as,to turn ON or OFF an insect repellent diffuser when little or no lightis detected. Similarly, lighting control systems used to control outdoorlights can be used to control the insect repellent diffusers, so thatthe networked insect repellent diffuser will follow the programmaticdirection of a lighting control system.

With respect to traffic flow, people detectors are sensors that cancount the number of times a person has walked past a specific point. Onedetector is a photoelectric sensor, which detects the number of times abeam of light, which is placed across a space, is broken or interceptedby a person walking past. Another detector is an image or video camera,which uses image processing techniques to determine the number of peoplein a space, as well as their individual dwell times. The diffusiondevice can take information from a traffic flow sensor and automaticallyadjust its scent diffusion, for example, by scenting an area as peopleare arriving, or increasing the scent level to accommodate a largertraffic throughput.

With respect to occupancy detection, these sensors can confirm thepresence of one or more individuals within a space. One approachincludes an image or video camera that uses image processing techniquesto determine the number of people in a space, as well as theirindividual dwell times. The diffusion device can take informationrelated to occupancy and automatically adjust its scent diffusion, forexample, by providing more scent to an area with more people, orstopping insect repellent from diffusion in an unoccupied area and thenbeginning diffusion of insect repellent upon the arrival of people.

With respect to proximity sensing, proximity sensors are triggered whena person is directly in front of a particular space, such as in front ofa particular product display. By sensing the presence of a person atthat space, the diffuser is able to provide a scent experience,coordinated with the presentation of the product in the display.

With respect to detection of a VIP/specific individual entering thespace, cameras with facial recognition software can determine thepresence and identity of an individual or individuals, whose facialprofiles have been pre-loaded for comparison. In another embodiment, theVIP/specific individual may be detected via detection of theirsmartphone. The presence of specific people can therefore becommunicated to the device from these sensors, allowing the scentdiffusion device to alter its performance.

With respect to insect repellent level, by “tagging” a desired insectrepellent with a molecular tag, such as a charged particle, a sensor maybe able to identify and determine the concentration of the “tagged”insect repellent particles within a space. The diffusion device can beset to deliver a certain level of scent concentration within anenvironment, and using odor detection of the scent particles which thediffuser is dispensing, can ensure a defined range of acceptable scentlevel, or “scent concentration factor” or SCF. When the sensor detectsinsect repellent concentrations below the desired SCF, then the diffuserdelivers additional insect repellent to achieve the desiredconcentration. If the measured concentration is within the defined SCF,then the diffuser continues monitoring without diffusion. If theconcentration is above the SCF, the diffuser can continue monitoringwithout diffusion, or can diffuse an odor sinking formulation whichbinds with airborne scent and thereby reduces the insect repellent levelto within the desired SCF range.

With respect to temperature, the scent diffuser may have multiple waysof measuring temperature. Internal temperature within the diffusiondevice is measured using a thermistor that is present in the electronicsof the device. This thermistor allows the device to communicate theinternal temperature to a remote monitoring center, which can be alertedif internal temperature exceeds a prescribed threshold such as itsrecommended operating range of temperature. Similarly, with remotemonitoring, the device can be pre-programmed to take certain actionunder certain temperature condition, such as, stop dispensing fragranceoil if the temperature is above its operating threshold, or below thefreezing point of the scent oil. External temperature may be measuredbased on a thermal sensor (thermistor) mounted externally to device,allowing the diffuser to alter its performance based on changingtemperatures within the environment which is being scented. Thetemperature of the exterior climate can also be retrieved from a remotedata structure, based on the geo-code location of the device using itsnetwork connectivity. The diffuser can react to the exterior temperatureof the environment, by diffusing alternate fragrances, or by alteringthe scent concentration. With all three forms of temperature measurementand tracking data across diffusers using the remote monitoringcapability of the devices, one can determine the statistical correlationof temperature to other performance trends, for example, oil consumptionrate over time.

With respect to humidity, a humidity sensor installed within a devicecan detect internal device humidity, one mounted externally to thedevice can determine environmental humidity within the space beingfragranced, and geocode and remote data lookups can be used to retrievethe humidity of the local climate. The scent device can react to changesin these humidity levels similarly as described for temperature.Similarly, over time, remote monitoring can be used to evaluate andcorrelate trend data, such as how humidity affects the consumption rateof scent oil within a diffuser.

With respect to time of day, the diffusers are smart, connected devices,and consequently, accurately know the time. Based on the geolocationdata from the cell phone modem (or network id) of a diffuser in a thescented environment, the device can accurately set its clock to thecorrect local time zone, and automatically adjust for seasonaladjustments in time, with the goal of keeping the diffuser unit intime-sync with the world clock. Since the scent diffuser devices havethe ability to change insect repellent output or type based on scentprograms or play lists, it is critical that the device has an accuraterepresentation of its current time.

With respect to season, the diffuser has the ability to accurately telltime as well as know the current day, week and year, using the sameapproach as described above. Using this knowledge of time, it can beprogrammed for different performance on different days or in differentseasons of the year.

With respect to a weather event, since the diffuser is smart andconnected, local weather conditions can be downloaded to the devicebased on its geolocation. Based on these local weather conditions, thediffusing device can alter its performance based on a predefined set ofrules.

The scent diffusion device may include at least one package containingan insect repellent oil or at least two packages containing an insectrepellent oil. In embodiment, one of the scent diffusion devices is amaster node and the other of the scent diffusion devices are slave nodesand receive control instructions from the computer through the masternode. In this embodiment, each scent diffusion device can adjust its owncontrol settings based on the activities of the other scent diffusiondevices. The method may include configuring the scent diffusion devicesso that a device duty cycle for one of scent diffusion devices does ordoes not occur simultaneously within proximity to another one of thescent diffusion devices. The scent parameter may relate to a targetedSCF goal. The method may further include determining the total number ofscent diffusion devices to dispose in the environment based on a roomvolume or area square footage. The method may further includedetermining one or more locations to dispose the scent diffusion devicesin the environment based on a room volume. The operation parameter mayinclude at least one of a flow rate of the liquid, a duration of flow ofthe liquid, a variation in the flow rate of the liquid, an on/off statusof the diffusion device, a package from which to diffuse the liquid, aswitch to a different package from which to diffuse the liquid, and thelike.

In another exemplary use scenario, the scent dispersion network includesone or more scent node devices and a wide-area network gateway device.In this scenario, the network gateway device performs the communicationand control functions of the scent gateway device, without actuallydispersing insect repellent. In this scenario, system administrators inthe NOC control the program settings of all networked scent devices, andensure insect repellent dispersion is conforming to effectivenessstandards or other parameters. This scenario provides remote andcentralized management of a scent dispersion network via a networkgateway device that does not dispense insect repellent.

In an aspect, a method of managing scent in an environment may includedisposing one or more scent diffusion devices within an environment,wherein the diffusion devices comprise a communications facility thatenables transmitting signals to and receiving signals from anon-dispensing, wide-area network gateway device. The method may furtherinclude networking the network gateway device to the scent diffusiondevices, wherein the network gateway device receives communication andcontrol functions from a remote computer for distribution to the scentdiffusion devices. At least one sensor disposed within the environmentmay transmit sensor data to the remote computer. At least one targetvalue of a scent parameter for an environment may be received at theremote computer. The method may further include controlling, via theremote computer, diffusion of a liquid, from a source of the liquid influid communication with at least one of the scent diffusion devices, toachieve the target value of the scent parameter, wherein controllingincludes setting or adjusting an operation parameter of one or more ofthe scent diffusion devices based on the sensor data. In embodiments, itis not diffusion of a liquid but diffusion of a gas. At least one of thescent diffusion devices receives control instructions from the remotecomputer and relays control instructions to at least one other scentdiffusion device. The scent diffusion devices may relay controlinstructions in series, in a ring, in a mesh, in a star networkingtopology, and the like.

In another exemplary use scenario, the scent dispersion network includesone or more scent node devices, a local area network control device, butwithout a wide-area network gateway device. Each scent node device ispaired with a local area network control device, which enables a localuser within a venue to program and control the scent node devicesindependently of a NOC (local control, versus centralized remotecontrol). This scenario enables local management of a scent dispersionnetwork via wireless local area network communication protocols.Examples of local area network control devices include a computer orlaptop with wireless local area network communication capability; asmart phone, pad device, or tablet computer with wireless local areanetwork communication capability; or a purpose built scent controllerdevice with wireless local area network communication capability. Inembodiments, the scent controller device may be a handheld orwall-mounted device for controlling one or more networked scent diffuserdevices.

In an embodiment, a method of managing scent in an environment, mayinclude disposing at least one scent diffusion device within anenvironment, wherein the at least one scent diffusion device comprises acommunications facility that enables transmitting signals to andreceiving signals from a standalone remote control device, receiving atleast one target value of a scent parameter for the environment at thestandalone remote control device, and based on the target value,controlling, via the standalone remote control device, diffusion of aliquid from a source of the liquid in fluid communication with the atleast one scent diffusion device to achieve the target value of thescent parameter. In embodiments, it is not diffusion of a liquid butdiffusion of a gas.

In an aspect, a method of managing scent in an environment may includedisposing one or more scent diffusion devices within an environment,wherein the diffusion devices comprise a communications facility thatenables transmitting signals to and receiving signals from a local areanetwork control device and networking the local area network controldevice to each of the scent diffusion devices, wherein the local areanetwork control device receives communications from and distributescontrol instructions to the scent diffusion devices. The method mayfurther include disposing at least one sensor within the environmentthat transmits sensor data to the local area network control device,receiving at least one scent parameter for scenting an environment atthe local area network control device, and controlling, via the localarea network control device, the diffusion of a liquid or gas, from asource of the liquid in fluid communication with at least one of thescent diffusion devices, to achieve the scent parameter, whereincontrolling includes setting or adjusting an operation parameter of oneor more of the scent diffusion devices in response to the sensor data.The local area network control device may include one or more of acomputer or laptop with wireless local area network communicationcapability, a smart phone, a pad device or tablet computer with wirelesslocal area network communication capability, a purpose built scentcontroller device with wireless local area network communicationcapability, a handheld device, a wall-mounted device, and the like.

In yet another exemplary use scenario, the scent dispersion systemincludes one or more scent node devices, with no wide-area networkgateway device and no local area network control device. This scenarioprovides for the stand-alone operation of a scent node device usingmanual settings, established by a local individual using the userinterface found on each insect repellent dispersion device.

In embodiments, multiple master devices may be deployed at a singlephysical location. In embodiment of multi-device installs (master-slaveconfiguration), each device can adjust its own control settings based onthe activities of the other devices. The system may be a coordinatednetwork of devices with “local scent network” level control mechanismsversus device stand-alone control mechanisms. For example, a group ofmeshed dispensers could be configured so that individual device dutycycles do not occur simultaneously within proximity to one another (onedevice waits for the previous one to dispense, so they do not end upoverloading an area with multiple scent devices “firing” at the sametime). Of course, they may also be configured to fire simultaneously. Ineffect, coordination, sequencing, and/or synchronization of meshed scentdevices is controlled dynamically.

In an embodiment, the number and location of scent diffusion deviceswithin an enclosed space may be established based on the volume of thespace but the individual control programs for those devices may be basedon something other than the volume of the space, such as a sensorreading, an area, a linear distance from the device to a target, and thelike. In embodiments, the initial settings for the diffusion devices maybe established in one manner, such as by using room volume, but then mayswitch over to control via a different mechanism, such as byenvironmental adjustments or rate of consumption measurements, and thelike.

In an embodiment, the diffusion devices may operate in a scent-castingmode, wherein the devices are programmed with a linear distance to ascent target location and the level of insect repellent that should beat that target location. Further considerations may include airflow andtonnage of an HVAC system when programming a scent-casting mode. In ascent-casting mode, the goal is not to fill the space with insectrepellent, but rather scent a targeted area or audience with the scentbrand impression.

In an aspect, a method of scent casting in an environment may includedisposing a scent diffusion device within an environment, wherein thescent diffusion device comprises a communications facility that enablestransmitting signals to and receiving signals from a remote computer,determining a distance from the scent diffusion device to a scent targetlocation, receiving, at the remote computer, at least one scentparameter for the scent target location, and controlling, via the remotecomputer, the scent diffusion device to achieve the scent parameter,wherein controlling includes setting an operation parameter of the scentdiffusion device based on the determined distance and the scentparameter. The method may further include disposing at least one sensorwithin the environment that transmits sensor data to the remotecomputer, and adjusting an operation parameter of the scent diffusiondevice in response to the sensor data. The sensor data may relate to atleast one of room volume, room geometry, room area, airflow, presence ofodor-producing materials, presence of odor-sinking factors, lighting,air flow, altitude, traffic flow, occupancy detection (IR, camera, CO2sensor), proximity sensing, detected odor, insect repellent level,temperature, humidity, time of day, season, weather event, and detectionof a VIP/specific individual entering the space (via smartphone ping orthe like). The method may further include adjusting an operationparameter of the scent diffusion device in response to an HVAC tonnage.

Scent casting in an environment may be accomplished using a network ofdiffusion devices, such as scent diffusion devices. A network ofdiffusion devices may be disposed within an environment that eachincludes a communications facility enabling that transmission of signalsto and the reception of signals from a remote computer. One suchreceived signal may be a scent parameter for a scent target location. Adistance from the diffusion devices to the scent target location may bedetermined by any means available for such determination. Via the remotecomputer, the network of diffusion devices may be controlled to achievethe scent parameter. Controlling may include setting an operationparameter of the diffusion devices based on the determined distance andthe scent parameter.

Scent casting may also be implemented using a hotspot in an environment.Such a diffusion device may include a sensor to determine a distancefrom the diffusion device to a scent target location and a firstcommunications facility 1022 that receives control signals from anetwork operations center, the control signals for controlling a scentdiffusion from the diffusion device in accordance with a scentimpression goal and the distance. The device may also include a secondcommunications facility 1024 to communicate data with a mobile device atthe scent target location for consumer engagement, such as to provideconsumers with a coupon, an ad, a survey, a game, or other content.

A ticketing & workflow facility of the NOC may receive alerts from thedevice management and monitoring system and create tickets. Tickets maybe routed, based on rules, to the correct person, or in some cases,rules might automatically trigger some action (e.g., shut down a devicethat is misbehaving, or reboot a device). The ticketing & workflowfacility may be a configured version of a commercial service ticketingsystem.

Managed, networked diffusion devices, where the device is agnostic tothe actual diffusion technology, may be used for generating a consistentscent profile in a wide area/ambient environment in accordance withbrand standards or other parameters. In an embodiment, generating theconsistent scent profile involves consistently neutralizing a malodor inan environment. Generating a consistent scent profile may includemanagement of duty cycle, schedule, insect repellent level/insectrepellent replenishment, room volume, room geometry, airflow, presenceof odor-producing materials, presence of odor-sinking factors, lighting,temperature, humidity, altitude, traffic flow, occupancy, time of day,inventory of particular “base,” “mid-” and “high” notes in a fragrancechord and other variables relating to the environment. As such, datacollected by or about the device, data based on measurements by sensorson or associated with the device, and data from users may be transmittedto, generated, or used by the NOC in order to facilitate management.These data will be described herein.

Certain data types may be sent from the diffusion devices to the NOC orother user. Data regarding a work schedule, such as duty cycle, dayparts, and the like, may be sent by the diffuser. Object type, such asthe type of diffuser (e.g. Master, Slave, standalone), may betransmitted by the diffuser. The diffusion device may transmit theinsect repellent name(s) and level(s). For example, the insect repellentlevel may be a value from 0 to 100, with 100 being full and 0 beingempty. The temperature, in Fahrenheit, Celsius or other units, as wellas date and time may be transmitted. The diffusion device may send anindication of the strength of the local wireless link. An array of anyerror codes that are currently present on the device may be transmitted.The diffusion device may transmit the average pump pressure.

The diffusion device may report diagnostic data on a periodic basis,such as weekly/daily, or by forcing the diffusion device into adiagnostic mode, such as via a local keypad or controller, or from theNOC. Data usage may be reported by Master devices, such as cellular datausage.

In an embodiment, a device management & monitoring (DM&M) facility maybe embodied in a user interface that may include configurable dashboardsto enable activities, such as viewing diffusion device telemetry data,viewing maps of diffusion device locations, receiving liquid levelreadings or other gauge/sensor readings, providing control instructionsto diffusion devices, review status of and manage scent operations forone or more networks of scent diffusion devices, receive data fromdevices, receive alerts, view/edit schedules and scent profiles, viewunitless parameter for articulating and displaying an insect repellentlevel, review alerts to replace packages, order new packages and payon-line, renew subscriptions for scent management services, reviewsystem health (e.g. machine down alerts), change permissions for a user,initiate a ticket/workflow, assign a service technician, add/removedevice from a network, add customer/division/store, and the like. Inembodiments, a mobile application, such as a smartphone or tabletapplication, may allow customers to access a mobile version of the userinterface.

The user interface may be used to set up and trigger alerts based onvarious criteria and configurable conditions (e.g., low liquid, machinedown, etc.), wherein the NOC may manage the system by exception based ondetected alarms. The user interface may allow customers to view thestatus of their diffusion devices, adjust their settings, or viewhistorical graphs showing the performance of the devices. The userinterface may take data from DM&M and present it in a way that uses thelanguage of fragrance, rather than of devices (e.g., MAC Address, PANnumber). In embodiments, the DM&M facility may be responsible for allcommunication with diffusion devices and may be the only module that canchange diffusion device settings. In other embodiments, WiFicapabilities may be included in the master diffusion device enabling adirect connection to the device.

The user interface may be used to manage and edit the schedules for oneor more diffusion devices independently of one another. That is, thereis the ability for different diffusers at a single site to havedifferent schedules.

A reports page may be used to generate and access reports. An “aboutpage” or introductory page may tell the user about the version number ofthe application, as well as the version number and device types of thevarious devices.

The user interface may include a login screen for entering the user'sUser ID and password and authenticating it. The user interface mayinclude a dashboard page that shows the status of all local diffusiondevices at a summary level. A visual icon representing each diffusiondevice with an indicator for function or status may be included in thedashboard. The user interface may include a diffusion device page thatincludes a list of diffusion devices at the location, with summarystatus and settings (e.g., volume setting, overall diffusion devicehealth, whether it's currently diffusing or not based on duty cycle,status of communications links, and the like). Icons for each diffusiondevice may be presented. A diffusion device status page may be adrill-down page that shows all device status data and settings, such asoverall diffuser health (good, or error+error code and description),diffuser volume/output-level setting (according to program), diffuservolume/output-level setting (according to setting by local customer,possibly overriding the program), liquid insect repellent level (basedon the sensor reading), time and date according to device clock, healthof communication links between various devices and the local server,which insect repellent is playing/being diffused in the diffuser, dateand time of last service, and the like. An edit diffusion devicesettings page may be a page where a user can edit a diffusion device'ssettings and save the new settings, including the on/off programsettings, and the insect repellent volume level.

A location control page may allow the user to increase or decrease theoverall output of all diffusion devices in the location. For example, analgorithm, such as a location control algorithm, may execute acalculation that translates a targeted insect repellent value (alsoknown as a local output level) (e.g., between 0-100, between 0-10, etc.)in the location to actual device settings for each diffusion device. Theuser would adjust only the overall location volume setting, not thesettings for each diffusion device. The NOC would then calculate andadjust the settings for each diffusion device needed to achieve theoverall location volume setting. The local output level represents theoutput level aggregated across all diffusers. The user interface maypresent graphical arrows for moving the output level up or down. Themaster diffusion device may adjust its own output level and the outputlevel of its slaves upward or downward, proportionately based on the newsetting. If all diffuser settings were the same, the new settings willall be the same, but if the diffusers had different output settings, thenew settings may be scaled based on each diffuser's original setting. Asan example, the current output level might be 70, based on 3 diffuserswhose output settings are 65, 70, and 75. If the user moves the outputlevel to 80, the new settings may be the original settings multiplied by(80-70)/70, resulting in settings of 74.28, 80, 85.71, respectively. Theabove calculations may be done by customer web services or the NOC andpushed to the individual diffusers.

The location control algorithm may include feedback from one or moresensors in the environment or onboard the diffusion device in making thecalculations, such as feedback from a Bluetooth/WiFi sensor (e.g. todetermine an occupancy), a different occupancy sensor, an altitudesensor, an airflow sensor, a humidity sensor, a light sensor, amotion/occupancy/proximity sensor, a laser distance measure/digitallaser rangefinder, a particle sensor, an olfaction sensor/VOC sensor, animaging sensor/cameras, a scent concentration factor sensor, a clock, atimer, a calendar, a weather sensor, and the like.

Modification or generation of a scent profile delivered bya network of scent diffuser devices may be based on feedback fromautomated air sampling, wherein modifying is by selection of oradjustment of the diffusion settings for one or more of a plurality ofavailable scent modifiers onboard one or more networked scent diffuserdevices. A user may adjust an overall level of insect repellent desiredin the space and the NOC or the master diffuser device may determine theadjustment required for the one or more devices, such as slave diffuserdevices. A master diffuser device may adjust its own output level andthe output level of its slaves upward or downward, proportionately basedon the new setting.
